Description:

T. Murray, owner of a single story frame house in Oakville, Missouri, a south county suburb of St. Louis. The garage had piers installed twice prior to 2006 within 3 years of each other. The first pier project had concrete piers installed to a depth of approximately 6 feet. The second pier project had a round steel "pipe" or "push" pier installed. These piers require, in part, the counter balance weight of the structure to assist in the installation process. Although the company that had installed the steel piers assured the customer that the piers would be installed to "bedrock" they were only installed to depth of approximately 4 feet. Helitech was hired to install galvanized Helical piers, which do not rely on counter balance weight for installation. The piers were installed to an average depth of 16-18 feet by placing the drivehead directly on top of the pier and driving the pier to competent load bearing strata. Helitech completed the installation in 2 days, providing a sound foundation on which the garage could finally rest.
